A block is pulled up a slope by a force Fp = 65 N (parallel to the slope) as shown in the figure below. The mass of the block is 8.0 kg. The slope makes an angle of 20° with the horizontal ground. The coefficients of kinetic and static friction between the box and the slope are μk = 0.20 and μs = 0.30, respectively. What is the net work done by all forces acting on the block if it moves a distance of 0.40 m up the slope?

Which of the following statements concerning the formal charge of an atom is/are true? 1. The formal charge of each individual atom in a molecule or ion is the actual atomic charge that can be determined experimentally. 2. The formal charge of each individual atom is always the same for each possible resonance form. 3. The sum of the formal charges of each atom in an ion equals the overall charge of the molecule or ion.

A 18.6-g piece of gold (s = 0.129 J/(g·°C)), initially at 285.4°C, is added to 147.2 g of a liquid, initially at 27.9°C, in an insulated container. The final temperature of the metal–liquid mixture at equilibrium is 28.9°C. What is the identity of the liquid? Neglect the heat capacity of the container.
